The Boundary Falls occurrence is 5.5 kilometres south of Greenwood, 900 metres west of Boundary Creek.

Regionally, this area of the Quesnel terrane is underlain by a wide-ranging section of largely volcanic and sedimentary Tertiary, Mesozoic and Upper Paleozoic rocks that have undergone several episodes of deformation and are intruded by fault-controlled diorite-monzodiorite and granodiorite.

The Boundary Falls property is underlain by Permo-Carboniferous basement complex Knob Hill Group mica schist, marble, amphibolitic schist and gneiss. Several intrusions are evident and consist of a predominant Tertiary diorite-monzodiorite and Cretaceous granodiorite. The units are metamorphosed and sheared in a northwest direction, with Jurassic and Tertiary faulting.

Mineralization in quartz veins appears to be associated with Tertiary diorite intrusives and is hosted in the intrusion and the country rock. Mineralization consists of pyrite, galena, tetrahedrite, sphalerite and chalcopyrite in a gangue of mainly quartz and occasional calcite; it also occurs in local silicified zones. Gold and silver values are associated with the sulphide mineralization.

A quartz vein system labelled the Glory Hole strikes northwest and dips 75 degrees southwest and appears to be hosted in a shear zone in Permo-Carboniferous Knob Hill Group mica schist close to the contact with a Tertiary diorite-monzodiorite intrusion. The vein is highly shattered and ranges from a few centimetres to 1.5 metres in width. Some stringer veins disperse into the wallrock. Limonite occurs as an oxidation product along fracture planes within the quartz vein. The vein is offset along strike by subparallel fault movements and contains locally semimassive pyrite with lesser galena and sphalerite.

Approximately 350 metres southeast of the Glory Hole and on the east side of the Tertiary diorite knoll, a massive quartz vein 0.5 to 1 metre wide, labelled the No. 1 Vein, strikes northeast and dips steeply northwest. Historical workings have exposed the vein over a strike length of 35 metres.

Mineralization on the Boundary Falls claims was first discovered in 1894. By 1897, a 12-metre shaft was being sunk, possibly near the No. 1 Vein.

In May 1975, Amigo Silver Mines Ltd. conducted a very low-frequency electromagnetic survey on the Boundary Falls claim group, outlining a northwest-trending, steeply south-dipping conductive zone (Assessment Report 5618).

Between October and November 1975, Amigo completed a 2093-line metre self-potential geophysical survey over the electromagnetic anomaly outline earlier in the year and five diamond drill holes totalling 336.5 metres. Two holes testing beneath the Glory Hole vein lacked encouraging results; the remaining three holes intersected barren quartz veins with enough pyrite and graphite present to account for the electromagnetic anomalies (Assessment Report 6067).

In 2002, InvestNet Inc. conducted limited prospecting activities, recovering high-grade gold samples from the No. 1 Vein and Glory Hole areas. Near the Glory Hole, a grab sample of semimassive pyrite with lesser galena and sphalerite assayed 69 grams per tonne gold, 2335 parts per million lead, 8341 parts per million lead and 100.6 grams per tonne silver with anomalous molybdenum, cobalt, arsenic, cadmium, bismuth and mercury (Assessment Report 28307).

In 2005, 730821 Ltd. conducted approximately 120 line kilometres of helicopter-borne time domain electromagnetic and magnetometer surveys. A prospective anomaly was identified coincident with a postulated north-plunging limestone anticline hinge (Assessment Report 28307).

In 2015 and 2016, Golden Dawn Minerals Inc. conducted an exploration program including 85 rock chip samples, and 1,770 metres of drilling between 17 holes. Chip sampling found high gold values in the lower Skomac vein, Glory Hole, and No 1 vein. High silver values were observed at the Skomac vein. Diamond drilling found the Skomac vein at and below the No 7 level and the historic lower Skomac No 1 level. Highlighted rock samples at Glory Hole was sample A2014156 grading 6.22 grams per tonne gold, and 10 grams per tonne silver (Ball, M. (2016-08-27): Technical Report on the Boundary Falls Property). Drilling was highlighted in hole BF16-24 across 0.25 metres grading 148 grams per tonne silver, and in hole BF16-11 across 0.74 metres grading 5.8 grams per tonne silver and 6.12 grams per tonne gold (Cowley, P., et al.
